This Same issue happned before with Redmi Note 12 Pro 4G... that 1.0.15 base was doing the same .... could it be the same error? hopefully these are fixed soon and THGMIXM 1.0.16 can be install without revised and re uploads .
After installing the rom the screenshot app is not recognised. so I downloaded 5 other screen shot apps, rooted the device, and disabled signature. one of them worked. problem is in the rom.
